TAOMSUN 752G / 722G / 721G Series Spectrophotometer – UV-Vis & Visible Spectral Analysis for Routine & Industrial Testing
Brand:TAOMSUN ｜Overseas Technical Support:METICULAB (Korea) ｜ISO 9001· Precision Optical Manufacturing
The752G / 722G / 721G Series Spectrophotometeris a reliable single-beam analytical instrument designed for routine laboratory quantitative analysis, industrial inspection, and multi-scenario testing. Three models are available to match different wavelength requirements:752G (UV-Vis, 200–1000nm),722G (Visible, 325–1000nm), and721G (Visible, 340–1000nm). All models adopt aholographic blazed grating monochromatorand a microcomputer measurement system, delivering stable wavelength accuracy, low stray light, and direct concentration reading. With a backlit LCD display, automatic 0%T / 100%T adjustment, and automatic light door technology, the series combines precise measurement with simple, efficient operation for daily lab workflows.
🔍 Core Features:Holographic blazed grating monochromator + imported photocell detector ensuring wavelength accuracy and reading precision; automatic light door technology protects the photoelectric sensor without requiring a black body; halogen tungsten lamp and long-life deuterium lamp (752G) ensure stable light source across UV-Vis range. Supports concentration direct reading, 30 concentration curve storage, and flexible cuvette configurations designed for research, industrial inspection, and production quality control.

❓ Frequently Asked Questions (FAQ)
Q: What is the difference between the 752G, 722G, and 721G?
A: The main difference is wavelength range. 752G is UV-Vis (200–1000nm), 722G is Visible (325–1000nm), and 721G is Visible (340–1000nm). Choose 752G if you need UV measurements; choose 722G or 721G for visible-light-only applications.
Q: What are the wavelength accuracy and repeatability?
A: Wavelength accuracy is ±2nm, and repeatability is ≤1nm across all three models.
Q: What is the photometric range and accuracy?
A: Photometric range is 0–100.0%T / 0–1.999A / 0–1999C, with accuracy of ±0.5%T, ±0.004Abs (0–0.5A), ±0.008Abs (0.5–1A).
Q: Does it support direct concentration reading?
A: Yes. Concentration factor can be set directly, and readings are displayed without additional calculation.
Q: What is the function of the automatic light door technology?
A: The automatic light door closes the optical path when not measuring, protecting the photoelectric sensor without requiring a black body, extending component lifespan and reducing maintenance costs.
Q: Can it accommodate other cuvette specifications?
A: Yes. The sample compartment accommodates 5–100mm cuvettes. The standard 1cm cuvette holder can be replaced with optional specifications.
Q: Is it suitable for export?
A: Yes. Export wooden case packaging, English manual, and 110V/220V customization are available. EXW / FOB / CIF terms are supported.
Q: What is the warranty?
A: One-year whole-machine warranty. Light sources and other consumable parts can be consulted for replacement.
